Performance Questions 225 vs. 360

I need to get a dog(s) in this fight. I consider myself one of the "kings" of "frugal" slant sixers. Just look at my signature. My 66 Cuda is street legal, total cost including the car, about $5,000. My 66 Valiant (drag car only) was running mid 13's first weekend out, and cost about $1,500 to build (including the car). My 65 Valiant was a NHRA stock eliminator car, that got a turbo added, with full exhaust, to be street legal. The turbo stuff could be done today for about $500-$600.
